What is vertigo?
Vertigo is a symptom characterized by the sensation of spinning or dizziness. It often feels like you or your surroundings are moving or spinning, even when you are perfectly still. It is not a medical condition on its own but rather a symptom of an underlying problem related to the balance and equilibrium system in the inner ear or the brain.
There are two main types of vertigo:
Peripheral Vertigo:
This type of vertigo is caused by problems in the inner ear, particularly the vestibular system, which is responsible for maintaining balance. The most common cause of peripheral vertigo is benign paroxysmal positional vertigo (BPPV), which occurs when tiny calcium crystals in the inner ear become dislodged and affect the balance signals. Other causes of peripheral vertigo may include vestibular neuritis, Meniere's disease, and labyrinthitis.
Central Vertigo:
This type of vertigo is related to issues in the brain or central nervous system that process balance and spatial information. Causes of central vertigo may include migraines, multiple sclerosis, brain tumors, and certain neurological conditions.
Symptoms of vertigo may include a spinning sensation, unsteadiness, loss of balance, nausea, vomiting, and difficulty concentrating or moving. The severity and duration of vertigo episodes can vary depending on the underlying cause.
If you experience recurrent or severe vertigo episodes, it is essential to seek medical evaluation to determine the underlying cause and receive appropriate treatment. A healthcare professional, usually an ear, nose, and throat (ENT) specialist or a neurologist, can perform a thorough evaluation and recommend the most suitable treatment for your specific condition.
Types of vertigo
Vertigo can be classified into two main types based on its underlying causes:
Peripheral Vertigo:
Peripheral vertigo is the most common type of vertigo and is typically related to problems in the inner ear or the vestibular system. The vestibular system is responsible for maintaining balance and spatial orientation. Conditions that cause peripheral vertigo include:
● Benign Paroxysmal Positional Vertigo (BPPV):
This is one of the most prevalent causes of vertigo. It occurs when tiny calcium crystals in the inner ear, called canaliths, become dislodged and disrupt the normal flow of fluid in the semicircular canals, leading to brief episodes of vertigo triggered by specific head movements.
● Vestibular Neuritis:
This condition involves inflammation of the vestibular nerve, usually caused by a viral infection. It results in sudden, severe vertigo that can last for days.
● Labyrinthitis:
This is an inflammation of the inner ear, often caused by viral infections such as the common cold or flu. It can lead to vertigo, hearing loss, and ringing in the ears.
● Meniere's Disease:
Meniere's disease is a disorder of the inner ear characterized by recurring episodes of vertigo, fluctuating hearing loss, ringing in the ears (tinnitus), and a feeling of fullness or pressure in the ear.
Central Vertigo:
Central vertigo is less common and is associated with problems in the central nervous system, particularly in the brainstem or cerebellum, which process balance and spatial information. Causes of central vertigo include:
● Migraine-Associated Vertigo:
Some individuals with migraines may experience episodes of vertigo, which can be associated with or without headache.
● Vertebrobasilar Insufficiency:
This condition involves reduced blood flow to the back part of the brain (vertebrobasilar system), leading to vertigo and other neurological symptoms.
● Multiple Sclerosis:
In some cases, multiple sclerosis can affect the nerves responsible for balance, causing vertigo.
●Brainstem Tumors or Lesions:
Tumors or other abnormalities in the brainstem can disrupt the normal balance and cause vertigo.
It is essential to differentiate between peripheral and central vertigo because their causes and treatments can differ significantly. If you experience vertigo or dizziness, it's crucial to consult a healthcare professional for a thorough evaluation and appropriate management.

■ Physical Examination:
A thorough physical examination will be conducted, with a focus on the nervous system, inner ear, and balance-related functions. The healthcare provider will check for signs of nystagmus (involuntary eye movements), balance disturbances, and other neurological abnormalities.
■ Vestibular Function Tests:
Various specialized tests may be performed to assess the function of the vestibular system (inner ear) and the patient's balance. These tests may include:
■ Dix-Hallpike Test:
This test is used to diagnose benign paroxysmal positional vertigo (BPPV). The patient's head is quickly moved into specific positions while the healthcare provider observes for characteristic eye movements and vertigo symptoms.
■ Videonystagmography (VNG):
VNG is a test that records eye movements using video goggles while the patient undergoes specific head movements and positional changes.
■ Electronystagmography (ENG):
Similar to VNG, ENG measures eye movements during specific tests to assess vestibular function.
■ Caloric Testing:
This test involves the introduction of warm or cold air or water into the ear canal to stimulate the vestibular system and assess its response.
■ Posturography:
Posturography measures balance and stability by having the patient stand on a special platform while their movements are recorded.
■ Imaging Studies:
In some cases, imaging studies such as magnetic resonance imaging (MRI) or computed tomography (CT) scans may be ordered to rule out structural issues in the brain or inner ear, particularly in cases of central vertigo or when other neurological conditions are suspected.
■ Blood Tests:
Blood tests may be conducted to check for infections, inflammation, or metabolic disorders that could be contributing to vertigo symptoms.
■ Evaluating Underlying Causes:
Since vertigo is a symptom, not a standalone condition, the healthcare provider will also try to identify any underlying medical conditions or factors that may be causing or contributing to the vertigo.
The diagnostic process may vary depending on the patient's specific symptoms and medical history. Once a diagnosis is established, the healthcare provider can create an appropriate treatment plan to address the underlying cause and manage the vertigo symptoms effectively.
